This premium replacement kit is engineered in the USA to deliver superior sealing, heat transfer, and oil control for your motorcycle's engine, providing everything needed for two pistons.\u003c\/p\u003e\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eDesigned for specific 3.750\" bore sizes with a +0.010\" oversize, this Hastings piston ring set is a critical upgrade for maintaining optimal engine health and power output. Each set includes top compression rings, second compression rings, and oil control rings, all crafted with precision. The \u003cstrong\u003eBarrel Face top compression rings\u003c\/strong\u003e are expertly designed to enhance heat transfer between the piston and cylinder wall, effectively controlling combustion chamber gases. This allows the piston to efficiently transfer the energy of expanding combustion gases directly to the crankshaft, maximizing power.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eNapier second compression rings\u003c\/strong\u003e feature a unique reverse twist and a taper-machined ring face, mimicking the scraping edge of a positive twist torsional ring. This innovative design promotes superior side sealing, preventing oil from being forced under and behind the ring, which significantly improves oil economy and reduces consumption. For meticulous oil management, the \u003cstrong\u003eThree Piece Flex Vent oil control rings\u003c\/strong\u003e utilize a three-piece design with rails manufactured for a small cross-sectional area, ensuring better conformability to the cylinder bore. This construction, combined with uniform pressure from four steel rails and two expanders, guarantees positive oil control. Furthermore, the \u003cstrong\u003eMoly coated piston rings\u003c\/strong\u003e provide enhanced durability and reduced friction, ensuring a long service life. Proudly made in the USA, this replacement piston ring set promises reliability and performance for discerning motorcycle enthusiasts and professionals.\u003c\/p\u003e\n\u003ch2\u003eFeatures \u0026amp; Highlights\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBarrel Face Top Compression Rings:\u003c\/strong\u003e Optimizes heat transfer and combustion gas control for efficient power delivery.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNapier Second Compression Rings:\u003c\/strong\u003e Advanced reverse twist design enhances oil scraping and side sealing, leading to improved oil economy.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThree Piece Flex Vent Oil Control Rings:\u003c\/strong\u003e Ensures superior bore conformity and uniform pressure for precise and positive oil control.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMoly Coated Ring Material:\u003c\/strong\u003e Provides increased durability and reduced friction for extended component life and smooth operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete Two-Piston Set:\u003c\/strong\u003e Includes all necessary rings for two pistons, simplifying your engine rebuild or maintenance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMade in the USA:\u003c\/strong\u003e Guarantees high-quality manufacturing and reliable performance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eStyle: Replacement\u003c\/li\u003e\n\u003cli\u003eUnits: Set\u003c\/li\u003e\n\u003cli\u003eProduct Name: Piston Ring Set\u003c\/li\u003e\n\u003cli\u003eBore Size: 3.750\"\u003c\/li\u003e\n\u003cli\u003eBore Oversize: +0.010\"\u003c\/li\u003e\n\u003cli\u003eRing Material: Moly Coated\u003c\/li\u003e\n\u003cli\u003eVendor Part Number: WG1254778 | 2M4805010\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eImportant to Know\u003c\/h2\u003e\n\u003cp\u003eThis set includes enough rings for two pistons.
